    • PROBLEM TO BE SOLVED: To provide a displacement estimation method for an object with which an error of an estimation amount can be reduced by estimating a displacement of an object to be measured or a point that a measuring device has not measured.SOLUTION: In an object, (n) pieces of members (r) are linked in an X-axis direction with a pin (l) as a rotation supporting point. In the object, a marker 10 is deposited onto each member (r), and a displacement (y) in a Y-axis direction (direction crossing an X axis) of each marker 10 at an X-axis direction position (x) is measured by a one-dimensional sensor. Then, a straight line passing through the pins (l) in both ends of each member (r) is represented by a linear expression, coordinates of each pin (l) are determined and further, a condition where an (n-1)th straight line crosses an n-th straight line is represented. From these expressions, a linear expression passing through the pins (l) in both the ends is determined for each member (r). From this expression, the displacement of any arbitrary point in the member (r) or tilting of each member (r) can be determined accurately.
